METALLIC LATHING.

Application tiled January 21, 1924. Serial No. 687,429.

To all whom t mag/- concern.' i

-Be it known that I, CHARLES H. SCAM- MELL, a citizen of the United States, residinvat New' York city, county of New York.,

and State of New York, have invented certain new and useful Improvements in vMetallic Lathing, fully described and represented in the following specification and the accompanying drawings, forming a" part of the same. 4

Metallic lathing with a backing sheet, e whether `waterproofed or not, for .con-

venience in shipment Iand use, is customarily supplied in rolls of varying lengths and of standard widths. In using this material to anchor the plaster for walls and ceilings, and also for inside and outside stucco work, it is necessary that such lathingbe fastened to studs or similar furring. According to present day practice, these studs or furring strips are usually positioned at standard distances apart, according to the width of the lathing to be used, and for proper support each lathing strip is stapled or nailed to at least three studs onfurrm strips, that is, a stud is provided at each e ge of the lathing and another in the center. Such studs not only provide a firm support for the lathin but will oiset it from a wall to be covere The studs to which theed es of the lathing strips or'sheets are secure also support the edges of adjacent lathing strips or .sheets which overlap thereon. This arrangement, of course, conoeals'the central stud from the workmansview, when the lathing is applied bg starting at the top of the wall, which 'is t e usual and most convenient manner of starting the work. It frequently happens, therefore, Vthat the workman is unable to definitely determine the proper point at which to insert the staples or nails through the lathing in order to properly engage the central studs Guesswork in this respect often results in the staples or .nails not taking a firm hold because of being too close to the edge of the studs, and in many instances missing the studs altogether, with the result that the backing sheet is mutilated' and, if a'waterproofng layer of material is present in the lathing, this also is punctured, so that the protective properties of the lathing are lessened, 4inaddition to the loss of time in securingthe lathingin place. The present improvement aims to overcome the above diiiiculties by providing simple. and lnexpensive means whereby lathing in` longl `strips or sheets,-afte`r being properlyv positioned andsecured to thestuds at the top and liottom ends, may be securely fastened to the central stud without experiencing the objections above named, because the line along which the staples or nails are to be inserted for securing thev lathing to the central studs` is clearly indicated. This enables the work to be properly and rapidly done, and results in a more durable structure by preventing mutilation of the backing sheet or waterproofing layer, if the latter be used,

To enable others skilled in the art to understand the invention, a preferred embodiment thereof will now be described in connection with the accompanying drawings, and the novel features then be pointed out in ,the claims.

' In the drawings- Figure 1 is a-faee view of a portion of a paper or fibre backed waterproofed metallic lathing applied to studs or similar furring. in a wall construction, and

Figure 2 is a section-on the line 2 of Fig. 1.

Referring now to the drawings, the studs 10 are secured in position in the usual way with respect to a joist 11 and the Iioor (not shown). These studs are usually placed parallel to and at standard distances apart, so as to receive standard Widths of metallic lathing, that is, a stud 10 is provided at each edge of a lathing strip and another centrally of such stri In applying metal lathing of the type re erred to, it is the usual practice to first secure the end of the rolled strip at the top of the wall and permit the remainder of the .roll to lie on the iioor until the desired length is cut 0H. The central stud, therefore, is concealed from the workmans View, and all of the above objectionable resultsensue. To overcome these difficulties, metal lathing of that type having a backing sheet, and with or without a protective layer of waterproofing material such as herein shown, is provided with a marker 1 which, in the preferred 'form shown,

is inserted between the metal lathing 2 and waterprooiing material 3, of asphalt or the I like, which is interposed between the lathing 2 and a fibre or paper backing Ll. The marker 1 is thus rmly held in position, and this is further assured if the. asphalt layer 3, when applied to the metal lathing in the course of manufacture, is softened by heat to favor adhesion thereto of the metal lathing 2 and the paper or libre backing sheet 4. This marker 1 -is preferably a textile` strand of `some bright color, such as red'or White, or any other color which will contrast strongly with the color of the lathing ma- .terial so as to be visible in locations where the light is poor. The workman is thus able to definitely locate the line on which the lathing is to be stapled or nailed to the central stud or similar furring, in both wall and ceiling constructions.

strand may be used, which may be otherwise a plied to the lathing to secure the results a ove described.

What I claim is:

1. A new article of manufacture, consisting of an elongated strip of metallic lathing having a backing sheet secured thereto and a marker consisting of a small strand be- Asheet and an interposed layer of Waterproofv ing inaterlal, and a permanent marker having a color contrast with the lathing material between said lathing and waterproofing layer positioned to indicate the location of studs or similar furring when said lathing is being applied.

3. A new article of manufacture, consisting of metallic lathing having a backing sheet and inter osed layer of waterproofing material secured thereto, and a marker consisting of a colored textile strand between said metal lathing and said Waterproofing layer,said marker being positioned to indicate the location of studs or similar furring when. said lathing is being applied.

In testimony whereof, I have hereunto set my hand.

CHARLES H. SCAMMELL.
